Compare and contrast health and disease.

Health is the condition of an animal in terms of how the functions of life are being performed while diseases are disturbances in the function of an animal. Both affect the behavior of an animal.

How does health affect behavior?

Health affects behavior of animals depending on good and bad health. If an animal is in good health, it will show a positive behavior, while an animal will bad health will show a negative, or bad behavior.

How does environment affect health?

The aspects of the environment of an animal can affect the well-being or health. How healthy or ill an animal is depends on the components of the environment such as temperature, light, and humidity.

How can the environment be manipulated for the benefit of an animal?

The temperature of an environment can change to better suit the animal using heat lamps and cool water. Light can also be provided to give heat. Proper ventilation can be added to remove humidity, thus removing microbes and bacteria that can harm animals.

What are some results of poor health?

Poor health can cause death, lower production, and human disease. Death causes the producer to lose profit and this can result in the increase of cost on the product. Lower productions also decreases profits for the producers. Human diseases can be contracted from products that came from poor health.

Explain the difference between contagious and noncontagious diseases.

Contagious diseases are diseases that spread by direct or indirect contact from other animals while noncontagious diseases are diseases that do not spread through casual contact. Unlike noncontagious diseases that can be caused by a nutritional, physiological, or neurological problem, contagious diseases are caused by pathogens.

List three diseases of animals and describe each.

1. Anthrax: an acute infectious diseases that frequently affects cattle and can cause fevers, rapid respiration, and swelling of the neck.
2. Bang's disease (brucellosis): attacks the reproductive tract of female cattle, sheep, and hogs.
3. Blackleg: an acute highly infectious disease that affects cattle, sheep, and goats that causes high fevers, swelling of the neck and shoulder, muscles in the neck, shoulder, and thighs cracked when mashed, and finally death.

How does the body fight off diseases?

The body fights off diseases using antibodies in the body. Antibodies such as leukocytes fight off pathogens and diseases.
